Another way would be to have a function which would play a sound for you and call it from where you need it - something like

procedure RingABell()
if version(2)=2   && development only
??chr(7)
endif
return ""

You could call that function from any error event, Catch clause, or even

assert lEverythingOK message "something fishy here"+RingABell()
